Model

NBD-HP1200-3680TIY-D

Electrical Spec

AC220V   4.5KW

Pressure selection at accessible temperature

Temperature varies with air pressure. Please refer to the table below for details:

High temperature and high pressure pipe belongs to consumables, when you find it deformation, please replace it in time.

Cavity specification

1. Size: sample constant temperature zone Φ36mm *250mm (more specifications, request, for you to choose)

The 2.1/4NPS internal thread interface is installed in the furnace tube air inlet, supporting high pressure air supply pipe

Note: High temperature and high pressure reaction tubes are consumables and are not covered by warranty.

furnace construction

1. Can open double-layer structure, conducive to the need for rapid cooling customers, shell surface temperature is less than 60℃

2. Nano high temperature alumina coating on the surface of the inner furnace can improve the heating efficiency of the equipment.

3. The furnace body is designed to be open, so as to load the material and replace the furnace tube.

Gas and crucible are available

1. Oxidation, protective atmosphere and inert gases, such as N2, Ar and He.

2. In order to avoid sample pollution, it is best to wrap the sample with gold foil or nickel foil into alumina or quartz boat, and then put it into the furnace tube for sintering, do not put the sample directly in the high-temperature and high-pressure tube without a crucible.

Control system

1. 15 temperature curves can be pre-stored, and 30 sections of "temperature-time" axis can be set for each curve, avoiding the trouble caused by repeated setting of different experimental processes;

2.NBD-101E embedded operating system Chinese and English interchange graphical interface, 7 inch real color touch screen input, intelligent man-machine dialogue mode, real-time heating power display, non-linear pattern temperature correction;

3. With over temperature and over pressure alarm, broken couple protection, leakage protection, differential pressure relief and other functions.

4. The first layer of protection: when the pressure value exceeds the customer set, automatically open the solenoid valve pressure relief;

The second layer of protection: when the exhaust pipe is blocked or the solenoid valve is damaged and the pressure is still rising beyond the pressure relief value, the temperature point system automatically sets the limit pressure, the equipment stops heating;

The third layer of protection: when the pressure is inaccurate due to the pollution of the digital sensor, or the program control system fails, the pressure continues to rise. When it reaches the upper pressure value set by the pressure relay of the safety analog signal, the power supply is directly turned off.

Heating element

Ferric chromium alloy doped molybdenum

Pressure detection and control

1. The high pressure chamber is installed with a pressure sensor, and connected with the control system, real-time display

2. The high pressure relief solenoid valve is installed on the flange. When the pressure in the furnace tube is higher than the set pressure value, the solenoid valve will automatically open and deflate, and the chamber pressure is maintained within the set pressure range. The maximum automatic relief pressure that the solenoid valve can bear is 15Mpa. When the pressure is higher than 15Mpa, the solenoid valve cannot be used for pressure relief. The series needle method should be closed and the manual method should be used for pressure relief.

Sealing of flange

1. CF flange structure drawing is as follows (using copper sealing ring)

The 2.1/4NPS internal threaded connection is installed on the furnace pipe flange, and a high pressure valve is installed at each end of the flange, and the right valve is equipped with a pressure gauge.

3. The flange is sealed with oxygen-free copper seal ring;

4. Optional torque wrench to avoid excessive tightening flange.

Cautions

The company's high temperature and high pressure furnace tubes are made of high temperature alloy steel, the highest temperature resistance of 1150℃, good ductility. When the air pressure inside the cavity exceeds the maximum tolerable value (exceeding the long-term strength of the alloy tube) due to misoperation, the alloy tube will creep and bulge at the weak place first, then crack will appear to release the gas. No high pressure cracking risk!

Service

1 year warranty with lifetime support (The warranty does not include consumable parts, such as furnace tubes and sealing rings).
